BWeaves, LOVE IT!
I love lobe wonder...wear them every day. Our wonderful pattye offers small try me packs in her Etsy shop.
Minasan, the 7mm refers to the cup size on the earring stud. Generally, you want the pearl to be at least 2-3 mm larger than the cup so that it fits the curve of the pearl. I don't have any earring findings in my stash right now, otherwise I would measure the peg width. My mind is thinking it is about 0.8 mm but may be a tad larger. Peg length can also be an issue if the peg is a tad longer than the drill hole length. Don't be surprised if you need to trim the end of the peg mounting to fit your pearl. I usually drill my pearls for earring mounts at 1.0 mm. I would definitely call Bella and ask them to measure it out for you. The larger backs come in a few different sizes and weights. Make sure that you get a backing that fits the post (not the peg) of the earring finding you want. It's kind of a lot of information, I know, and it might be easier just to order a set from Rio Grande. On the glue, I prefer to use gel based super glue (mentioned by Pareltje above) rather than two part epoxy. I find it very easy to work with and very very secure. A very little bit goes a long way...you need just a small drop or two, depending on the cup, the peg and the pearl. And please be sure to measure and check the fit BEFORE you apply any glue. With a stud, you really don't have to worry about pearl position, but with a dangle style, you will want to mount the pearl with any obvious blemishes toward the back of the setting rather than the front. Good luck to you and I cannot wait to see your finished project!
